FIELD OF THE INVENTION

The present invention relates to a pair of glasses, and moreparticularly to a pair of glasses with a wearing cushion device using anair pump to perform inflation.

BACKGROUND OF THE INVENTION

With increasing development of science and technology, various 3Cproducts are introduced into the market. Since the demands of modernpeople on the 3C products become higher and higher, the burdens onpeople's eyesight are heavier. As a result, the average age that peoplestart needing to wear glasses is lowering, and the population wearingglasses is increasing. Thus, the manufacturers pay attention to theimprovement of the aesthetically-pleasing appearance and the wearingcomfort of the glasses.

Generally, the temples of the commercially available glasses areone-piece plastic structures, or the temples are metal bracket withplastic material earmuffs. That is, the parts of the temples contactingthe ears are made of the plastic material. Since the plastic material isa hard material, the ears are uncomfortable when the glasses are worn.Moreover, the temples of the commercially available glasses cannotcompletely match the shapes of the user's ears. Under this circumstance,the glasses may fall down from the ears readily, thus damaging theglasses or causing danger if the user is taking exercise or driving.

Currently, some kinds of silicone hooks are commercially available. Thesilicone hooks are for being sheathed around the rear parts of thetemples. When the glasses are worn by the user, the user's ears arehooked by the silicone hooks and thus the possibility of falling downthe glasses is reduced. However, the process of sheathing the siliconehooks around the temples is troublesome. Moreover, because of thesilicone hooks, it is more difficult to put on and take off the glasses.In addition, the silicone hooks also cannot completely match the shapesof the user's ears. That is, the silicone hooks result in foreign bodysensation. Consequently, the overall comfort of wearing the glasses isimpaired.

Therefore, there is a need of providing a pair of glasses with a wearingcushion device in order to increase the wearing comfort and safety.

SUMMARY OF THE INVENTION

An object of the present invention provides a pair of glasses with awearing cushion device, which is comfortable and safe, resolving theproblems with conventional glasses in which the ears feel uncomfortableand the glasses easily fall off while wearing.

In accordance with an aspect of the present invention, there is provideda pair of glasses with a wearing cushion device. The glasses include amain body, at least one inflatable cushion, an air pump, a switchelement, a control unit and an air channel. The main body includes atleast one temple. The at least one inflatable cushion is disposed on asurface of the at least one temple. The air pump is in communicationwith the at least one inflatable cushion. The control unit iselectrically connected with the switch element and the air pump. The airchannel is embedded within the main body and in communication with theat least one inflatable cushion and the air pump. When the switchelement is turned on, the switch element issues an enabling signal tothe control unit and the control unit enables the air pump in responseto the enabling signal. When the air pump is enabled, an ambient gas istransferred to the at least one inflatable cushion through the airchannel, so that the at least one inflatable cushion is inflated withthe gas and expanded.

The above contents of the present invention will become more readilyapparent to those ordinarily skilled in the art after reviewing thefollowing detailed description and accompanying drawings, in which:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention will now be described more specifically withreference to the following embodiments. It is to be noted that thefollowing descriptions of preferred embodiments of this invention arepresented herein for purpose of illustration and description only. It isnot intended to be exhaustive or to be limited to the precise formdisclosed.

FIG. 1 is a schematic perspective view illustrating the outer appearanceof a pair of glasses with a wearing cushion device according to anembodiment of the present invention. As shown in FIG. 1, the glasses 1comprise a main body 10, a first inflatable cushion 11 a, a secondinflatable cushion 11 b and a switch element 14. The main body 10comprises a first temple 101 a, a second temple 101 b and a frame 102.The first temple 101 a and the second temple 101 b are connected to afirst end and a second end of the frame 102, respectively. The firsttemple 101 a and the second temple 101 b are foldable, but not limitedthereto. The first inflatable cushion 11 a is located at a distal end ofthe first temple 101 a and attached on a surface of the first temple 101a. The second inflatable cushion 11 b is located at a distal end of thesecond temple 101 b and attached on a surface of the second temple 101b. Preferably but not exclusively, the first inflatable cushion 11 a andthe second inflatable cushion 11 b are one-piece expandable structures.Moreover, the outer shells of the first inflatable cushion 11 a and thesecond inflatable cushion 11 b are made of a soft elastic material. Forexample, the soft elastic material includes but is not limited to asilicone material. The switch element 14 is located at the second temple101 b. For example, the switch element 14 is a button, but not limitedthereto.

FIG. 2A is a schematic perspective view illustrating the inner portionof the glasses according to the embodiment of the present invention.FIG. 2B is a schematic exploded view illustrating the glasses accordingto the embodiment of the present invention. In this embodiment, theglasses 1 further comprise an air pump 12 and an air channel 13. The airchannel 13 is a soft hollow tube for communicating gas, being embeddedwithin the main body 10 and in communication with both the firstinflatable cushion 11 a and the second inflatable cushion 11 b. The airpump 12 is also in communication with the air channel 13, so that theair pump 12 can introduce the gas into the air channel 13.

In an embodiment, the first inflatable cushion 11 a and the secondinflatable cushion 11 b have a first inflating hole (not shown) and asecond inflating hole (not shown), respectively. Meanwhile, the airchannel 13 comprises a first channel opening (not shown) correspondingto the first inflating hole and a second channel opening (not shown)corresponding to the second inflating hole. The size and location of thefirst channel opening match those of the first inflating hole, and thesize and location of the second channel opening match those of thesecond inflating hole. As a result, the first channel opening can beconnected to the first inflating hole to communicate gas between the airchannel 13 and the first inflatable cushion 11 a. Similarly, the secondchannel opening can be connected to the second inflating hole tocommunicate gas between the air channel 13 and the second inflatablecushion 11 b.

Please refer to FIGS. 2A, 2B and 3. FIG. 3 is a schematic functionalblock diagram illustrating the architecture of the glasses according tothe embodiment of the present invention. In this embodiment, the glasses1 further comprise a control unit 16 and a battery 17. The battery 17provides electric power for powering the control unit 16. The controlunit 16 is electrically connected with the air pump 12 and the switchelement 14 for receiving signals from the switch element 14 andaccordingly controlling the air pump 12. When the glasses 1 are worn bythe user, the first inflatable cushion 11 a and the second inflatablecushion 11 b are respectively contacted with the two ears of the user.When the switch element 14 is turned on, the switch element 14 issues anenabling signal to the control unit 16. In response to the enablingsignal, the control unit 16 enables the air pump 12 to transfer the gasinto the first inflatable cushion 11 a and the second inflatable cushion11 b through the air channel 13. Being inflated with the gas, the firstinflatable cushion 11 a and the second inflatable cushion 11 b expand tofit the ears of the user. As a result, the glasses 1 is securely worn onthe ears of the user and does not easily fall off, which is more safeand comfortable than conventional ones.

In the above embodiment, the inflatable cushions 11 a and 11 b arelocated at the distal ends of the temples 101 a and 101 b. It is notedthat the locations of the inflatable cushions 11 a and 11 b are notrestricted. For example, in another embodiment, the inflatable cushions11 a and 11 b extend inwardly on the inner surfaces of the temples 101 aand 101 b to reach a position that is able to be in contact with theuser's face. Hence, when the air pump 12 is enabled to introduce the gasinto the inflatable cushions 11 a and 11 b through the air channel 13,the inflatable cushions 11 a and 11 b are expanded to fit and to beattached on the user's face. Consequently, the inflatable cushions 11 aand 11 b can be fixed more stably. Under this circumstance, the comfortof wearing the glasses 1 is enhanced. In a further embodiment, anadditional inflatable cushion is attached on the frame 102 or otherparts of the temples 101 a and 101 b that are able to be contacted withthe user's face. Consequently, the comfort of wearing the glasses 1 isfurther enhanced.

Please refer to FIG. 3 again. In this embodiment, the glasses 1 furthercomprise a gas pressure sensor 18. The gas pressure sensor 18 iselectrically connected with the control unit 16 and in communicationwith the air channel 13 for sensing the pressure of the gas in the airchannel 13. The gas pressure sensor 18 may be embedded within the mainbody 10. If the gas pressure sensor 18 detects that the pressure of thegas within the inflatable cushions 11 a or 11 b is higher than athreshold value, the gas pressure sensor 18 issues a disabling signal tothe control unit 16. In response to the disabling signal, the controlunit 16 disables the air pump 12. Consequently, the pressure of the gaswithin the inflatable cushions 11 a or 11 b is adjusted to be in aspecified range, and the expansion amounts of the inflatable cushions 11a and 11 b are adjustable. Since the inflatable cushions 11 a and 11 bare not excessively expanded, the pressure applied to the user's ears iscomfortable.

Please refer to FIGS. 1, 2A, 2B and 3 again. In this embodiment, theglasses 1 further comprise a pressure valve structure 15. The pressurevalve structure 15 is embedded within the main body 10 and incommunication with the air channel 13. Meanwhile, the pressure valvestructure 15 is in communication with the exterior of the glasses 1through an exhaust hole 15 a of the main body 10. The pressure valvestructure 15 is a switchable valve structure comprising a check valve(not shown) and a relief valve (not shown). The check valve allows thegas in the air channel 13 to flow in only one direction withoutbackflow. The relief valve is used for adjusting the pressure of the airchannel 13.

The pressure valve structure 15 is electrically connected with thecontrol unit 16. When the air pump 12 is enabled by the control unit 16in response to the enabling signal, the gas is transferred through theair channel 13 in one direction without backflow due to the check valveof the pressure valve structure 15. When the switch element 14 issues apressure-relief signal to the control unit 16, the control unit 16controls the relief valve of the pressure valve structure 15 to decreasethe pressure, and the gas is exhausted from the inflatable cushions 11 aand 11 b to the surroundings through the air channel 13, the pressurevalve structure 15 and the exhaust hole 15 a, sequentially.Consequently, the pressure in the air channel 13 is properly adjusted,or the inflatable cushions 11 a and 11 b are restored to the deflatedstate. The user can deflate the inflatable cushions 11 a and 11 b ordecrease the pressure thereof before putting the glasses in thenon-usage state. Therefore, since the inflatable cushions 11 a and 11 bare not continuously in the high pressure state, the use lives of theinflatable cushions 11 a and 11 b are extended.

FIG. 4B is a schematic exploded view illustratingthe air pump of the glasses according to the embodiment of the presentinvention and taken along a rear side.

In an embodiment, the air pump 12 is a piezoelectric air pump fordriving the gas. In this embodiment, the air pump 12 comprises aresonance plate 122, a piezoelectric actuator 123 and a covering member126.

The resonance plate 122 is aligned with the piezoelectric actuator 123.The resonance plate 122 comprises a central aperture 1220. The centralaperture 1220 is formed in a middle portion of the resonance plate 122.

The piezoelectric actuator 123 comprises a suspension plate 1231, anouter frame 1232 and a piezoelectric element 1233. Preferably but notexclusively, the suspension plate 1231 is a square suspension plate. Thesuspension plate 1231 comprises a middle portion 1231 c and a peripheryportion 1231 d. When the piezoelectric element 1233 is subjected to thecurvy vibration in response to an applied voltage, the suspension plate1231 is subjected to the curvy vibration from the middle portion 1231 cto the periphery portion 1231 d.

The two ends of the bracket 1232 a are connected with thesuspension plate 1231 and the outer frame 1232, respectively.Consequently, the bracket 1232 a can elastically support the suspensionplate 1231. The conducting pin 1232 b is protruded outwardly from theouter frame 1232 so as to be electrically connected with an externalpower source (not shown). The piezoelectric element 1233 is attached ona second surface 1231 b of the suspension plate 1231. The length of aside of the piezoelectric element 1233 is smaller than or equal to thelength of a side of the suspension plate 1231, but not limited herein.When the piezoelectric element 1233 is subjected to deformation inresponse to an applied voltage, the suspension plate 1231 is subjectedto a curvy vibration.

The covering member 126 comprises a sidewall 1261, a bottom plate 1262and an opening 1263. The sidewall 1261 is protruded from the edges ofthe bottom plate 1262. Moreover, an accommodation space 126 a is definedby the sidewall 1261 and the bottom plate 1262 collaboratively. Theresonance plate 122 and the piezoelectric actuator 123 are accommodatedwithin the accommodation space 126 a. The opening 1263 is formed in thesidewall 1261. The conducting pin 1232 b of the outer frame 1232 isprotruded out of the covering member 126 through the opening 1263 so asto be electrically connected with an external circuit (not shown), butnot limited herein.

The air pump 12 further comprises a first insulation plate 1241, aconducting plate 125 and a second insulation plate 1242. The firstinsulation plate 1241 is located over the conducting plate 125. Thesecond insulation plate 1242 is located under the conducting plate 125.The shapes of the first insulation plate 1241 and the second insulationplate 1242 substantially match the shape of the outer frame 1232 of thepiezoelectric actuator 123. The first insulation plate 1241 and thesecond insulation plate 1242 are made of an insulating material (e.g. aplastic material) for providing insulating efficacy. The conductingplate 125 is made of an electrically conductive material (e.g. ametallic material) for providing electrically conducting efficacy. Theshape of the conducting plate 125 substantially matches the shape of theouter frame 1232 of the piezoelectric actuator 123. Moreover, theconducting plate 125 has a conducting pin 1251 so as to be electricallyconnected with an external circuit (not shown). Similarly, theconducting pin 1251 is protruded out of the covering member 126 throughthe opening 1263 so as to be electrically connected with the controlunit 16.

FIG. 5A is a schematic perspective view illustrating the piezoelectricactuator of the air pump according to the embodiment of the presentinvention and taken along the front side. FIG. 5B is a schematicperspective view illustrating the piezoelectric actuator of the air pumpaccording to the embodiment of the present invention and taken along therear side. FIG. 5C is a schematic cross-sectional view illustrating thepiezoelectric actuator of the air pump according to the embodiment ofthe present invention.

In this embodiment, the suspension plate 1231 is a stepped structure.That is, the suspension plate 1231 comprises a bulge 1231 e. The bulge1231 e is formed on the first surface 1231 a of the suspension plate1231 and located at the middle portion 1231 c. For example, the bulge1231 e is a circular convex structure such as a cylinder. In someembodiments, the suspension plate 1231 is a square plate structure withtwo flat surfaces without the bulge 1231 e.

Please refer to FIG. 5C again. A top surface of the bulge 1231 e of thesuspension plate 1231 is coplanar with a first surface 1232 c of theouter frame 1232, and the first surface 1231 a of the suspension plate1231 is coplanar with a first surface 1232 a′ of the bracket 1232 a.Moreover, the bulge 1231 e of the suspension plate 1231 (or the firstsurface 1232 c of the outer frame 1232) has a specified thickness withrespect to the first surface 1231 a of the suspension plate 1231 (or thefirst surface 1232 a′ of the bracket 1232 a). A second surface 1231 b ofthe suspension plate 1231, a second surface 1232 d of the outer frame1232 and a second surface 1232 a″ of the bracket 1232 a are coplanarwith each other. The piezoelectric element 1233 is attached on thesecond surface 1231 b of the suspension plate 1231. In some otherembodiments, the suspension plate 1231 is a square plate structure withtwo flat surfaces. That is, the structure of the suspension plate 1231may be varied according to the practical requirements. In thisembodiment, the suspension plate 1231, the outer frame 1232 and the atleast bracket 1232 a are integrally formed and produced by using a metalplate (e.g., a stainless steel plate). Moreover, at least one vacantspace 1234 is formed between the suspension plate 1231, the outer frame1232 and the bracket 1232 a for allowing the gas to go through.

The inner structure and the outer structure of the air pump 12 will bedescribed as follows. FIG. 6 is a schematic cross-sectional viewillustrating the air pump of FIGS. 4A and 4B. From top to bottom, thecovering member 126, the second insulation plate 1242, the conductingplate 125, the first insulation plate 1241, the piezoelectric actuator123 and the resonance plate 122 of the air pump 12 are stacked on eachother sequentially, wherein the peripheries of the piezoelectricactuator 123, the first insulation plate 1241, the conducting plate 125and the second insulation plate 1242 are coated with glue to form a gluelayer 128. The glue layer 128 is filled in the accommodation space 126 aof the covering member 126 and seal the peripheries of the components.Consequently, the air pump 12 is assembled.

The air pump 12 has a square profile. It is noted that the profile ofthe air pump 12 may be varied according to the practical requirements.Moreover, the conducting pin 1251 (not shown) of the conducting plate125 and the conducting pin 1232 b of the piezoelectric actuator 123 areprotruded out of the covering member 126 so as to be electricallyconnected with an external circuit. After the air pump 12 is assembled,a first chamber 127 b is formed between the covering member 126 and theresonance plate 122. Moreover, a convergence chamber 127 a is defined bythe sidewall 1261 of the covering member 126 and the resonance plate 122collaboratively.

In this embodiment, there is a gap g0 between the resonance plate 122and the piezoelectric actuator 123. Moreover, a filler (e.g. aconductive adhesive) is inserted into the gap g0. Consequently, thedepth of the gap g0 between the resonance plate 122 and the bulge 1231 eof the suspension plate 1231 can be maintained to guide the gas to flowmore quickly. Moreover, due to the proper distance between bulge 1231 eof the suspension plate 1231 and the resonance plate 122, the contactinterference is reduced and the generated noise is largely reduced. Insome embodiments, the height of the outer frame 1232 of thepiezoelectric actuator 123 is increased, so that the gap is formedbetween the resonance plate 122 and the piezoelectric actuator 123.

When the piezoelectric actuator 123 is actuated to perform agas-collecting operation, the gas is introduced into the convergencechamber 127 a through the opening 1263 of the covering member 126,transferred to the first chamber 127 b through the central aperture 1220of the resonance plate 122, and temporarily stored in the first chamber127 b. When the piezoelectric actuator 123 is actuated to perform agas-releasing operation, the gas is transferred from the first chamber127 b to the convergence chamber 127 a through the central aperture 1220of the resonance plate 122 and transferred to the air channel 13 throughthe pressure valve structure 15.

The operations of the air pump 12 will be described as follows. FIGS. 7Ato 7D schematically illustrate the actions of the air pump according tothe embodiment of the present invention.

Please refer to FIG. 7A, which shows an initial state of the air pumpnot in action. After the covering member 126, the second insulationplate 1242, the conducting plate 125, the first insulation plate 1241,the piezoelectric actuator 123 and the resonance plate 122 of the airpump 12 are stacked on each other sequentially, the air pump 12 isassembled. There is a gap g0 between the resonance plate 122 and thepiezoelectric actuator 123. The convergence chamber 127 a is defined bythe sidewall 1261 of the covering member 126, the resonance plate 122and the bottom surface 201 a of the receiving part 201 collaboratively.The first chamber 127 b is formed between the covering member 126 andthe resonance plate 122.

Please refer to FIG. 7B. When the piezoelectric actuator 123 of the airpump 12 is actuated, the piezoelectric actuator 123 is vibrated upwardlyin response to the applied voltage. Consequently, the ambient gas isintroduced into the air pump 12 through the opening 1263 of the coveringmember 126. After the gas is converged to the convergence chamber 127 a,the gas is transferred to the first chamber 127 b through the centralaperture 1220 of the resonance plate 122. Due to the resonance effect ofthe suspension plate 1231 of the piezoelectric actuator 123, theresonance plate 122 is vibrated in a reciprocating manner. That is, theresonance plate 122 is subjected to an upward deformation. Meanwhile,the position of the resonance plate 122 corresponding to the centralaperture 1220 is protruded upwardly.

Please refer to FIG. 7C. The piezoelectric actuator 123 is vibrateddownwardly and has returned to its original position. Meanwhile, thebulge 1231 e of the suspension plate 1231 of the piezoelectric actuator123 is close to the central aperture 1220 of the resonance plate 122.Consequently, the gas in the air pump 12 is transferred to andtemporarily stored in the upper portion of the first chamber 127 b.

Please refer to FIG. 7D. The piezoelectric actuator 123 is vibrateddownwardly. Due to the resonance effect of the piezoelectric actuator123, the resonance plate 122 is vibrated downwardly. Due to the downwarddeformation of the resonance plate 122, the volume of the first chamber127 b is shrunken. Consequently, the gas in the upper portion of thefirst chamber 127 b is pushed toward peripheral regions of the firstchamber 127 b. Then, the gas is transferred downwardly through thevacant space 1234 of the piezoelectric actuator 123, and transferredthrough the central aperture 1220 of the resonance plate 122. From theabove discussions, it can be seen that when the resonance plate 122 isvibrating along the vertical direction in the reciprocating manner, thegap g0 between the resonance plate 122 and the piezoelectric actuator123 is helpful to increase the amplitude of vibration of the resonanceplate 122. That is, the proper gap g0 between the resonance plate 122and the piezoelectric actuator 123 allows the maximum amplitude ofvibration of the resonance plate 122. Then, the resonance plate 122 isreturned to the original position of FIG. 7A.

The processes of FIGS. 7A to 7D are repeatedly done. Consequently, thegas is continuously introduced into the convergence chamber 127 athrough the opening 1263 of the covering member 126, and transferred tothe first chamber 127 b. Then, the gas is transferred from the firstchamber 127 b to the convergence chamber 127 a. Consequently, the gascan be transferred stably. When the air pump 12 is operated, the gas issequentially transferred through the opening 1263 of the covering member126, the convergence chamber 127 a, the first chamber 127 b and theconvergence chamber 127 a.

As mentioned above, after the air pump 12 is enabled, the gas isintroduced into the air channel 13 through the pressure valve structure15 and the gas is transferred to the first inflatable cushion 11 a andthe second inflatable cushion 11 b through the air channel 13. Since thefirst inflatable cushion 11 a and the second inflatable cushion 11 b areinflated with the gas, the first inflatable cushion 11 a and the secondinflatable cushion 11 b are expanded and attached on the ears of theuser. That is, the glasses 1 can be securely worn on the ears of theuser while achieving the safe and comfortable purposes.

From the above descriptions, the present invention provides a pair ofglasses with a wearing cushion device. The user may turn on the switchelement to inflate the inflatable cushions with the gas. Consequently,the inflatable cushions are expanded and attached on the ears of theuser. In other words, the inflatable cushions are adjustable accordingto the shapes of the user's ears and securely fixed on the ears. Sincethe possibility of falling down the glasses is minimized, the safety ofusing the glasses is increased. Moreover, the glasses have the gaspressure adjusting function. The gas pressure sensor is used fordetecting the gas pressure within the inflatable cushions. The controlunit is used for controlling the gas pressure to be in a specifiedrange. Since the inflatable cushions are not excessively expanded, thepressure applied to the user's ears is comfortable. In case that theglasses are in the non-usage state, the user may turn off the switchelement to reduce the pressure and deflate the inflatable cushions.Under this circumstance, the use lives of the inflatable cushions areextended.
